There’s been a disturbance in the Force, and we’re not talking about Jar Jar. The title of the next installment in the “Star Wars” franchise was revealed on Monday: Star Wars: The Last Jedi.” The release date for the movie, written and directed by Rian Johnson, is Dec. 15.

Here’s what we know and don’t know, as well as some things we can safely assume, about Episode VIII. Or, as we imagine Yoda might say, “We know and know not, there is much.”

1. “Luke, I am your … daughter,” maybe? 

We know that Mark Hamill, who played Luke Skywalker in the original trilogy, is in the next film. He briefly appeared at the end of “Star Wars: The Force Awakens” in 2015, and will play a larger role here. In “The Force Awakens,” one of the main plot points centers on Rey, played by Daisy Ridley, and her journey to discover where Luke is hiding. There are also hints that Luke and Rey are related — but this is not confirmed. In an interview with USA Today, Mr. Johnson said the new movie would certainly explore the relationship.

Last February, Disney released a short teaser video announcing production on Episode VIII, showing the island where Luke and Rey reunite, with brief snippets of Mr. Hamill and Ms. Ridley on set.

2. There is no trailer yet.

So use the Force and imagine for now.

3. We don’t know what Princess Leia’s involvement will be.

Carrie Fisher, whose iconic Princess Leia captivated generations of fans, wrapped her work for “The Last Jedi” before she died in December. However, it is unclear how her character will be involved in the new movie or in the films beyond Episode VIII. The Hollywood Reporter cited insiders who said that multiple scenes featuring Ms. Fisher’s character were planned, but whether those plans have changed isn’t clear. (Ms. Fisher’s daughter, Billie Lourd, appeared in “The Force Awakens” and is on the cast list for “The Last Jedi” as well.)

4. We do not know much about the plot.

There are some morsels, though. In the USA Today interview, Mr. Johnson said the new movie would focus on “what’s going on with Luke Skywalker,” as well as the back stories of central returning characters from “A Force Awakens,” including Rey, Finn (a former stormtrooper, played by John Boyega) and Poe Dameron (a pilot in the Resistance, played by Oscar Isaac).

Also, Tom Hardy might put in an appearance. He is rumored to be making a cameo, but was very cryptic when asked about it in an interview with The Hollywood Reporter. “Ah, the internet is a glorious web of deceit and misinformation, isn’t it?” Mr. Hardy said.
